I'm afraid I haven't been following the list very closely lately. Too much other stuff going on... including a visit to the hospital in Montego Bay, Jamaica (long story). But I am interested in whatever Roger has to say. Can you provide the link?

As I just posted in the laconic thread between me and Mike about this, a
Bayer sensor of 16 MP is closer to 8 MP in actual resolution. This
generally isn't confusing, as virtually all sensors have the same (or
Fuji's X similar) limitation. But when doing theoretical calculations
assuming that they actually resolve as would say a Foveon, the Oly HR
mode or a much higher res imager downsampled, there's a mismatch in
assumptions that makes the result wrong.

In case you haven't been following, check out his link to Roger at
Lensrentals.com for some practical examples of diffraction. The
calculations may be "correct", except for not always agreeing with what
people see.
